Modification Design Summary

Tokyo Itsukaichi CC took on the challenge of remodeling to one green using a unique three-way system, and over a three-year period beginning in 2009, completed construction of 27 holes on the West, South, and East Courses, in that order.
The first is a directly managed project (no general contractor is used and a specialist is brought in to staff the site). Second, the architect is a coordinator (coordinating role), whose role is to consolidate the opinions of the club's board of directors, each committee member, and members, and reflect them in the on-site construction. The third is eco-friendly remodeling work. The elevation difference of the risky holes was mitigated by using construction debris in Tokyo, resulting in a significant image enhancement.
The organizer of this itinerary was Mr. Masayoshi Kobayashi. (Former president, current advisor, 30 years of competing against clubs, 0 handicap)

About Modification Theme

Mr. Tadashi Shimamura

In reviewing the design, we decided to incorporate a pond on the par 3 holes to make them unique and memorable, and to make the par 5 holes more dynamic and strategic.
The greens have been converted to one green with an average area of 600 square meters. The contours of the greens have been clarified and space has been created around them, eliminating trouble zones that could lead to OBs and allowing for recovery shots.
Beach bunkers are placed in the water on the 7th hole (570y, par 5) on the South Course.
The reverse-reddish green along the water slopes from deep right to left, and the more the pin is on the right, the more difficult the hole becomes over the hazard. The basic concept of the slope is "easy to understand and difficult," and a simple slope line (large undulation) is used to avoid a snake line.

Each green has a unique guard bunker, and the combination of the guard bunker and the green is intended to create variety. The bunkers were thought of as "signposts" that show the entrance to the greens by their location, size, and orientation.

The realization of eco-friendly construction

Mr. Kobayashi

There was construction work to convert the Keio Line line near Chofu into an underground tunnel, and the construction debris from this work was used to remodel the course. The size of the leftover soil was approximately 100,000 to 150,000 m3. The total cost of the project was approximately 800 million yen, but the company received 300 million yen in income from the disposal of the leftover soil, which greatly contributed to the economic benefits of the project.

Policy on topographical changes using residual soil

Mr. Shimamura

A major theme was the elimination of ups and downs throughout the hall.
On the 4th hole of the West Course (502 yards, par 5), the ground of the narrow fairway at the ravine was raised 6 to 8 meters with soil. Trees on both sides were also cut down to widen the ball flight space.
The sharply sloping fairway of No. 6 on the South Course, which used to be a signature hole, was gently sloped, and the par 5 hole was divided into two holes, a par 4 and a par 3. To compensate for this, holes No. 2 and No. 3 were connected as par 5 holes to maintain the par balance.
